Abstract

PURPOSE: A method for producing a TV stereoscopic image using a spectral filter and viewing the TV stereoscopic image is provided to broadcast stereoscopic moving pictures. CONSTITUTION: An image is produced such that red is arranged in front, green is arranged behind red and blue is arranged behind green on a black background(S10). Front and rear colors are judged based on perspective of the image in an editing process(S20). A color arrangement order based on the perspective of the image and a color chromaticity depth order are compared(S30). When the color arrangement order is different from the color chromaticity depth order, shading of a corresponding color is controlled(S40). Color sizes, a degree of overlapping and chromaticity are controlled such that a spacial position is noticeable(S50). Edition is completed to finish production of a broadcasting image(S60). A viewer watches the produced image wearing spectral filter glasses(S70).

Description

TV stereo-graph image production in use of the spectrum filter and its viewing method}

The present invention relates to a three-dimensional image production method that allows to watch a stereoscopic video on a general TV, full color (Full Color) by wearing a simple filter glasses (paper glasses) without wearing an electronic glasses (LCD Flic) in a general TV It relates to a three-dimensional video production method that allows you to watch a three-dimensional video.

In general, there are a number of ways to produce a three-dimensional video, there are also a number of ways to watch the produced three-dimensional video. But most of them have their own problems.

A typical image has two axes, the x- and y-axes whose projections are represented by these two axes. In computer monitors, the x-axis is the horizontal axis and the y-axis is the vertical axis. There is another axis, which is the z-axis, representing the depth and depth of the image. The general stereoscopic format represents perspective using the difference between the x-axis and the y-axis of the left and right images. This method is a method in which two images are overlapped with one of the left and right images. This method requires expensive 3D glasses and 3D video converter equipment and can cause eye fatigue when used for a long time.

For example, in the case of stereoscopic video using complementary color contrast such as red and blue glasses, full color is virtually impossible to express, and in the case of stereoscopic video using electronic glasses such as electronic glasses, the vertical of the current TV There are problems such as flickering due to the frequency or the need to purchase expensive electronic glasses in order to watch 3D video.

In other words, in order to prevent the human eye from flickering, a vertical frequency of 60 Hz is required for the left and right images, and for this purpose, the vertical frequency of the TV should be 120 Hz. However, currently sold TVs have a vertical frequency of 60 Hz and are divided into two in order to view a stereoscopic video and operated at 30 Hz for each of the left and right images. Therefore, even when using electronic glasses, TV images flicker due to their frequency characteristics.

Because of these problems, it is impossible to broadcast stereoscopic video in the case of public broadcasting to the public.

Accordingly, the present invention has been made to solve the above-described problems, the general audience without the filter glasses for viewing the stereoscopic video to provide the same image as a normal video, the audience with a filter glasses for viewing stereoscopic video The purpose of the present invention is to provide a stereoscopic video with a sense of space and to provide a TV stereoscopic video production and viewing method using a spectroscopic filter that can broadcast stereoscopic video in public broadcasting.

Normal Visual Reality according to the present invention does not use the x-axis and the y-axis of the image, but uses the color of the image and uses the z-axis, that is, the depth value, of the property of the color itself. It is a way to make the stereoscopic.

This method eliminates the need for expensive stereoscopic glasses and three-dimensional image converter mechanisms required by conventional stereoscopic methods.

First of all, the existing stereoscopic method cannot see the image properly without expensive stereoscopic glasses and stereoscopic image converter mechanism. The reason is that as described above, using the x-axis and y-axis of the left and right images, the two images are seen simultaneously without a device that binds the two images together.

However, the present invention (NVR) by using the z-axis of the color (Color) itself can be seen comfortably as seen on a normal TV when not wearing stereoscopic glasses, when wearing stereoscopic glasses can be viewed as a stereoscopic image immediately.

Such a method of achieving the present invention is a three-dimensional image production method, when producing a three-dimensional image, the color of the image in front of the red (Red), the middle of the green (Green), the back of the blue (Blue), black ( Black) arranging on the background to produce an image; Determining a front and back color due to the perspective of the image in the editing process; Comparing the arrangement order of colors due to the perspective of the image with the chromaticity depth of the colors themselves; Adjusting the contrast of the corresponding color if the color chromaticity depth of the corresponding position is different from the order of the color arrangement order by perspective; Adjusting the color position, overlapping degree, and chromaticity of the image together with the contrast adjustment to make the position of the space stand out; Complete the editing process to complete the production as a broadcast video, wearing a spectroscopic filter glasses on one side using a spectroscopic filter and the transparent film on the other side wearing a spectroscopic filter glasses so that you can feel a three-dimensional effect by binocular parallax It is characterized in that it is made to watch a three-dimensional image.

Hereinafter, exemplary embodiments of the present invention will be described in detail with reference to the accompanying drawings.

Figures 1a and 1b is a flow chart for producing a three-dimensional animation in accordance with the method of the present invention illustrating the production flow of the three-dimensional animation and shows that there is no difference from the production process of the general animation.

As shown in FIGS. 1A and 1B, the present invention is manufactured by applying a phenomenon in which light is separated like a rainbow as in the principle of prism when light passes through a spectroscopic (rainbow) filter. Each of the light separated by color forms its own shift phenomenon, which can be used as a left (or right) image by matching the shift of binocular parallax. In this way, a stereoscopic image can be realized with only one image (movie).

2 is a three-dimensional image production flowchart for viewing a three-dimensional image using the spectroscopic filter according to the present invention. This is a three-dimensional image through the process of applying the color standard by the color chart and design process in the manufacturing process of Figures 1a and 1b, and through the three-dimensional control process by the color array and chromaticity depth according to the present invention in the mapping reference map creation and stereoscopic setting process To produce.

In the stereoscopic image production method, when producing a stereoscopic image, the color of the image is placed in front of the red (Red) in the front, green (Green) in the middle, blue (Blue), black (Black) on the background Producing a step (S10); Determining a front and rear color due to the perspective of the image in the process of producing and editing the image (S20); Comparing the arrangement order of the colors due to the perspective of the image and the order of chromaticity depths of the colors themselves (S30); Adjusting the contrast of the corresponding color when the color chromaticity depth of the corresponding position is different from the order of the color arrangement order by perspective (S40); Adjusting the color of the image, the degree of overlap, and the color of the image together with the contrast control to make the position of the space stand out (S50); Completing the editing to complete the production of the broadcast video (S60); At the time of viewing, a spectroscopic filter is used on one side and a transparent film is used on the other side, and the spectroscopic filter glasses for viewing a stereoscopic effect by binocular parallax are worn (S70).

The most important choice in the image production of the present invention is color selection. The most basic color is red, green and blue on a black background. RED is the front, GREEN is the middle, BLUE is the back, and BLACK is the background color. This means that, as mentioned above, R, G, and B themselves have depth values, or Z axes.

If only three colors, R, G and B, are used on the black background, there will be a lot of restrictions in the video production because there is a limit on the number of colors. However, the present invention (NVR) may use colors of the color spectrum such as rainbow colors in addition to R, G, and B, which also uses depth values of the colors themselves. The order of the color depth values is as follows.

"red,-> orange,-> yellow,-> yellow-green,-> green,-> blue-green,-> blue,-> dark blue,-> black"

From this point of view, all colors have their own depth values, so there is no restriction on the use of color. However, care should always be taken in arranging colors according to the depth value of the image. In addition, the position of the space may be expressed differently according to the color contrast, the size, and the degree of overlap, so pay close attention to this.

On the other hand, one of the things to be aware of when making the image of the present invention to be broadcast on TV is the adjustment of the contrast. The image is formed not only by the depth value of the color but also by the contrast. When the depth value of the color matches the depth value of the contrast, an excellent stereoscopic image is formed.

Second, there are rules of font, color, and size in subtitles of TV images. First of all, the font has the most stereoscopic effect, such as the Gothic font, which is thick and hard.

The combination of fine text and background color is as follows.

* Black or dark green text on light cyan background

* Green text on dark green background

* Dark green or black text on green background

* Red text on black background

* Black text on Red background

* Magenta text on white background

* Cyan text on white background

* White on magenta background

Subtitles are input by selecting the most suitable combination based on the combination of the letter color and the background color.

Figure 3 schematically illustrates how a stereoscopic image produced by the method of the present invention is viewed through the glasses. In addition, the second image is a cut of the three-dimensional video produced by the method of the present invention, it is confirmed that there is no difference from the general image when viewed without wearing glasses.

Figure 4 is a device that can watch a three-dimensional video produced by the method of the present invention in the form of a simple paper glasses, a spectroscopic (rainbow) filter is attached to the left side and a transparent transparent vinyl attached to the right side. And it is confirmed that the design of eyeglasses can be made in various forms according to the needs of the marketing market.

There are several types of spectral filters or rainbow filters, and the spectral filter used in the present invention uses a filter in which spectroscopy occurs only in one (single) direction. Through this spectroscopic filter, light such as fluorescent lamps and surrounding objects are formed when the spectrum of light is formed on the left and right sides. This is also the basic principle of producing the image on the left and right sides of the place. In other words, when the spectrum of light is formed, the most widespread color (Red) becomes the frontmost object.

The order of the color depth values mentioned above is consistent with which color is the most widespread. In conclusion, if you use a unidirectional spectroscopic filter for the left filter of the glasses and a normal transparent film (vinyl) for the right filter, the image you see through the left filter will be spread out in one direction by the color depth value. In other words, the left eye makes an image to be seen, and the image seen through the right filter becomes a normal image that we usually see. When these two images are combined, the human brain recognizes it as a stereoscopic image instead of a normal image.

According to the present invention, when broadcasting a three-dimensional video in public broadcasting, users with filter glasses can watch a three-dimensional video with a sense of space, and a user without filter glasses can watch a general video, and can broadcast a three-dimensional video even on a broadcast. Will be. In addition, in the production of stereoscopic video, like the stereoscopic video using the binocular car that requires the image data of each of the left and right images, it occupies only one data storage space instead of each image data, so that the separate eyes need separate storage space. Data can be stored at a lower cost than car stereoscopic video.
